Quotes corner
Anthony Joshua: "People have asked me if it will be a special moment if I win and I say no because I know I belong here. I know what I’m capable of doing.
"When I regain those belts, I’ll keep cool and stay focused.
"It’s not a time to celebrate. It’s a time to keep the challenger’s mindset and move on to my next target.
"One by one, I’m picking them off and Ruiz is just the next target on my list."
Andy Ruiz Jr: “I want him to be mad and swinging in the ring, I want him to have that attitude because I will be calm and know exactly what we need to do.
“I don’t know if I am his bogeyman, I think his style was just perfect for me and I think it will be the same.
“I think he will box around nicely for four or five rounds until I take the pressure to him, start hitting his body and mixing it up.
“I did say he was not good enough to avoid me for the full 12 rounds, on the backfoot, we have been working on this for a round three months now and I know, whatever he brings, we will be ready for it.
“The doubters were just wondering, ‘What happened to Anthony Joshua? There’s something wrong with him.’
“Truly I think it was my style. It was the way that I handled him and that I took his punches.
“He gave me the hardest punches that he has so I ate them and that is what we are going to be doing again.”
